Configuring the IGMP Proxy

To enable the IGMP proxy functionality, you need to define which interface shall be used to receive multicast streams (upstream interface) and to which interfaces the multicast streams shall be forwarded (downstream interfaces). The router then listens on the downstream interfaces for IGMP join messages and forwards them to the upstream interface.

Mode: Context IP

Step	Command	Purpose
1	node(ctx-ip)[ctx-name]#	Go to the IP interface, which shall act as the IGMP proxy
	interface <if-name>	upstream interface
2	node(if-ip)[if-name]# igmp	Define the interface as the IGMP proxy upstream interface
	interface-type proxy-
	upstream
3	node(ctx-ip)[ctx-name]#	Go to an IP interface, which shall act as an IGMP proxy down-
	interface <if-name>	stream interface
4	node(if-ip)[if-name]# igmp	Define the interface as an IGMP proxy downstream interface
	interface-type proxy-
	downstream
5		Repeat steps 3 & 4 for any additional interface, which shall act
		as an IGMP proxy downstream interface.
